Custom tone curve

When I adjust RGB values on the curve (eg I pull down the blue to warm things up a bit) the "linear" in the option menu below the curve changes to "custom". When I then change the tone curve to medium or strong contrast, it nicely obeys and thus so, but what then surprises me is that the Blue curve in the RGB settings is again totally flattened out...does it retain the prior adjustment or does it just ignore it ? I only noticed just now on a relatively ok picture so it's easily enough to check but still it's odd that an earlier slider adjustment seems to disappear.
Anyone who can enlighten me on this ?
Tx. Frederic

Not sure if I understand. Let me try to explain my workflow : usually i start with camera profile (i'm a landscape guy) then basic panel tweaks,color temp if needed, a bit of the cool shadows/highlights, some blacks,clarity etc. then perhaps a graduated filter or lens profile...i hardly ever use the contrast slider (I never liked it in previous LR versions and haven't really touched it now) - BUT then my next move usually is to fool around with the tone curve, before (LR3) mostly via the sliders, now (LR4) mostly via the presets (linear,medium,strong) because I get confused between highlights/whites in BP then highlights/lights etc in TC panel, so I don't bother with those sliders in the TC panel anymore and I just click the presets. Now at long last back to my question : sometimes I try to use the new tone curve RGB to correct a blue tone or so, and then the preset name changes into "custom" and at the same time the curve nicely slopes the way I nudged it. When I then click on one of the presets in tone curve to L,M, or Strong the curve readjusts again.if I then check back on RGB blue channel again there is a nice straight diagonal as if nothing ever happened but the color tone seems to be preserved..net net it seems to do the right things to the pictures but the curve tells something different and that's what I don't get...
Sorry for the all the talk but I don't know how to explain it better. Perhaps I should just post a video of the dam thing.
Cheers. Frederic

Problem with custom tone curves

I have a problem with saving custom tone curves and don't know what to do about it. I am running Lr 5.7.1. on OS X 10.10.3 but I know this problem was there on OS X 10.10.2.
The problem is as follows, if I create a tone curve a try to save it Lr does not save it in under /Users/{UserID}/Library/Application Support/Adobe/CameraRaw/Curves as it should; instead it places it under /Users/{UserID}/. As a result the custom tone curve does not appear in the Point Curve list.
2 items of additional/useful information:
1) I can literarily see the Save dialog jumping from the correct folder, /Users/{UserID}/Library/Application Support/Adobe/CameraRaw/Curves, to the incorrect folder, /Users/{UserID}/
2) If I manually move the file to right location it appears in the Point Curve list
I have checked permissions and the User ID has Read/Write access. I have also made visible hidden folders with no luck.
Any suggestions are very welcome.

Hi,
To the details of an Infotype :
View the record in PA20, to make sure the PERNR has a record for the Infotype
Make sure the parameters passed to HR_INFOTYPE_OPERATION are correct :
Rather than passing them directly, pass :
g_pernr type p_pernr value pernr
g_infty type prelp-infty value 9402
Lock the PERNR with BAPI_EMPLOYEE_ENQUEUE
Read values
SELECT * FROM <table>        INTO CORRESPONDING FIELDS OF <wa>
        WHERE pernr = g_pernr
        AND begda   <= sy-datum
        AND endda   >= sy-datum.
ENDSELECT.
Perform HR_INFOTYPE_OPERATION.
Provided you fill all the key fields : SUBTYPE,OBJID.... RECORDNUMBER. (passed from p9008)
Why ?:
For an Emp, a number of records may be created, depending on the Time constraint of the Infotype
Say when you modify, the actual record may be delimted to sy-datum and a new record may be inserted
To learn more about Time constraints refer : http://help.sap.com/saphelp_nw04/helpdata/en/f4/51d2c9a79911d189550000e8216659/frameset.htm
Basline : BEGDA and ENDDA are very important in determining which record to modify!!
Unlock PERNR with BAPI_EMPLOYEE_DEQUEUE
The above should take care of No data stored for 9402 in the selected period
Regards,
Ravi

Where are the Tone Curve presets in the Lightroom Presets folder?

Hi
I have recenty had to reinstall all my software, and manged to find most of my old Lightroom settings in the Lightroom Presets folder (inside the Appdata folder on a PC) but I seem to have lost my custom tone curves.
Do you know which folder they should be in (indise the Lightroom Presets folder)
Thanks in advance
PS: I STILL don't understand why there are TWO comminty forums for Lightroom; it just doesn't make sense to me?!

Tone Curve in DNG Profile Editor

Is it possible to load a Point Curve from Adobe Camera RAW into the DNG Profile Editor as aTone curve?
I know you can enter the data again in the DNG Profile Editor in the Tone Curve Tab, but I develop the curve using Adobe Camera RAW and have it saved as a Point Curve.

Rob, I looked at the both a curve xmp file and a profile recipe that contained a custom tone curve with a text editor. The profile recipe has a lot of information and it's not easy to locate the tone curve data. I think it's easier at the present time to input the individual points in the tone curve tab of the DNG Profile Editor. Maybe Adobe will add this capability at some point.

Saving custom tone mappings

I'm trying to save custom tone mapping curves for later reference and use. I can record the "action" of constructing the curve in Image > Adjustments > Curves and applying it to an image. Unfortunately the "actions" panel does an incomplete job of describing this. Instead of reporting where all 16 control points were set, it reports the resulting first 72 of the 256 mappings, like so:
emulate ektachrome
          Curves
          Preset Kind: Custom
          Adjustment: curves adjustment list
          curves adjustment
          Channel: composite channel
          Mapping: 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5, 5, 6, 6, 6, 7, 7, 7, 8, 8, 9, 9, 10, 10, 11, 11, 12, 13, 13, 14, 15, 16, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 29, 30, 31, 32, ...
The ellipsis is Photoshop's, not mine.
How to verify what's in an already created mapping curve "action"? I can make a tone scale, apply the mapping to it, and then take RGB data off the result. There must be a simpler way than that. Where are custom "actions" stored? Can the files be read? Can they be edited?
Also is there any way to input a tone mapping curve purely numerically and skip the control points business?
Thanks.

Thanks Zeno Bokor. The hardest part was finding the actions panel menu!
Saving the action set did produce an .atn file, here attached.
It's hardly gibberish. Notepad shows how it works. BinEditor 2.0 reveals it completely.
Look at what precedes the repeating word "long" (written 6C 6F 6E 67). After 32 (written 20) comes 34 (written 22), then 35, 36, 37, 39, 40, 41, 43, 44, 45, 47, 48, ...
Note: I had to change the extension of the attachment for the Forum to accept it. You can knock off the .txt.

Tone Curve in Profile Help

Hey all,
Hoping the more talented tech gurus can help me out a bit here?
I have custom camera profiles for each of my cameras, so that my colour is consistent across bodies. They're all dual illuminant, some made in the old DNG profile editor, more recent ones in the Lightroom plug in from Xrite (Passport).
The colour is excellent, but I always find the tone to be too contrasty for my preference. When I look at the values on the step chart (greyscale patches) part of the McBeth checker they are not uniform / linear but rather already hold a contrast adding tone curve. What I do in Lightroom is to take the TAT tool in the curves panel and move these points per patch until they are almost "linear" again. In effect I apply a custom inverse S or reverse S to the image. I then save this curve per camera and invoke it on import setting along with the colour profile. I LOVE, LOVE the files I now get with this calibration, skin tones especially.
BUT
I now have my curve area of Lightroom being used essentially for calibration purposes, which robs me of it's use for creative purposes. Thus, I'd like to do this tonal adjustment at the profile stage, in the .dcp file to free me up to use the curve panel to suit my artistic vision.
SO
The question is how do I visually target the tone curve in DNG Editor (or passport) to match those which I have created in the curve panel now? I can eyeball it so they look similar, but it's a bit vague. Either that or a way to visually adjust the tone curve while viewing the grey swatches within the DNG editor?
The result should be the same as my custom camera profile plus my bespoke lightroom tone curve but all done in the .DCP file.
Am I missing something? Willing to be schooled always!
Many thanks if you made it this far.
(Note: I have posted this in LuLa too, so apologies to those who may frequent both)

Adobe Standard profile for 5D mark II includes tone curve?

In ACR, I see a "Point" tone curve with the "Adobe Standard" profile on Canon 5d Mark II files.
I've never seen a tone curve before on standard profiles for other cameras. I understand that tone curves are included in the camera standard, faithful, portrait and landscape profiles in attempt to match the in-camera jpegs. But I thought the Adobe Standard profiles were supposed to target only color (hue/sat) and leave tone up to the user.
Can someone verify that your system includes a point tone curve on 5D2 raws. Maybe my config is messed up.

Dear Eric,
I have Photoshop/Bridge CS3 and Camera Raw Version 4.5.0.175 on Windows XP (SP2).
To "see" tone curves I launch Bridge, navigate to a folder, double-click a raw or DNG file and get the ACR window.
In the ACR window, I click on the "Camera Calibration" tab and navigate through the various Camera Profiles.
For each profile, I click on the "Tone Curve" tab and view both the "Parametric" and "Point" curves.
For canon 5D Mark II DNG files there is always a "Medium Contrast" Point Curve, under every camera profile. I do not have a Canon 1Ds Mark III, but I have downloaded a sample raw file and converted it to DNG. For this DNG I also see a Medium Contrast Point Curve under every profile.
For my Canon 20D and Canon 1Ds raw or DNG files the Point and Parametric curves are flat under every camera profile.
When I downloaded the latest DNG converter and DNG Profile Editor, I'm reasonably confident I also downloaded and installed the most current camera profiles.
For Canon 5D2 files I see the following profiles: Adobe Standard, Camera Faithful, Camera Landscape, Camera Neutral, Camera Portrait, and Camera Standard, in that order.
For the Canon 1DS Mark III image I see all those profiles, plus ACR 4.4 and ACR 4.3
For Canon 20D files I see all those profiles, plus ACR 4.4 and ACR 2.4
To make sure I'm not picking up any presets, I have invoked the pop-up menu in ACR and selected "Reset Camera Raw Defaults". Then, for each file viewed in ACR I checked the pop-up menu again to make sure "Camera Raw Defaults" was checked.
And a reminder, all this was after I had created a number of custom profiles from Macbeth Color Checker images using the DNG Profile Editor. Those custom profiles created a problem with Bridge previews, so I removed all of them before viewing Point Curves as described above. Still hoping to get some feedback on the Bridge preview problem I described in this message:

LR4: tone curve settings lost after upgrade

I've find an annoying bug in this new version that makes me really crazy.
I've a Nikon D300S and a D7000.
After the importation of the catalog in the new Lightroom 4 all the D7000 .dng files have lost all the tone curve settings (I normally use linear).
The D300S files instead retain the tone curve settings.
It's a very strange behaviour: I've lost more than half of my old photo settings.
It's really frustrating.
Will be resolve soon this problem?
Until that day, for my older works I'll be obliged to continue to use LR3.

I've probably found a sort of workaround!
I've made some "organized" tests and here I report my findings.
Using LR3.5, I prepared a "test catalog" using 4 images from 7 different cameras (28 images total): for each of them, I used both the original nef and the dng converted file (56 files in the catalog), all develop process was set to "2010".
The cameras were Nikon D70, D90, D200, D300s, D700, D5000, D7000.
I applied a strong tone curve to each image in a way that the appearance was heavily characterized.
Before exit LR3.5, I SAVED ALL THE METADATA TO THE FILES.
Opening and converting the catalog using LR4, doesn't show any visual change until I zoom in library or open the develop module: both these operation lead to a flat image with the strong tone curve lost.
Curiously, the history retains the original steps but they are ineffective: histogram and tone curve changes according to the visual change but for some camera the "new" tone curve is "medium contrast", for others (D5000, D90) is "linear", for D300s is "custom" (linear with blacks cut at 9.8%, and this explain my initial impression that D300s's curves were untouched, sorry). This last behavior may depend on the fact that I've different default develop settings depending on the camera serial number.
Finally, the update to the 2012 process only minimally changes the visual appearance and surely doesn't restore the lost tone curves.
And here is the UNEXPECTED WORKAROUND: doing a READ METADATA FROM FILES IT RESTORES THE TONE CURVES (and the 2010 process)! Upgrading the process to 2012 minimally changes the visual appearance again but now the strong tone curve is present and evident.

LR4 Tone Curve default

Why in LR4 is the Tone Curve default set to Custom with a contrast lowering curve? I would like the default to be linear, but I can't remember how I set that up in LR3.

You probably had a preset for your camera in default develop settings, set to LR3- linear tone curve?
And now you have changed it into LR4- linear and have saved this as new develop default?
On this forum we prefer to share findings, so that others can benefit from by reading about it... It is not enough if just your particular issue is solved.

CS6 and Custom Point Curve vs. Linear

So when I open a new D700 shot in ACR with CS6 and go to the point curve panel it defaults to Custom. Which appears to have about 10-12 points on it and looks like it is providing a slight lift in the shadows and a slight dip in the highlights. I can select linear and I know how to save this as the new default I'm just curious what the Custom curve is and where it comes from. I'm using the V.4 Neutral profile if that makes any difference.
I've not seen this mentioned anywhere. Anyone understand it?

Highly unlikely, me-thinks.
But again, you can do it yourself using DNG Profile Editor.
I wish I could find the link, or the data you need, but can't.
But here is what I did: I used PV2010 linear in Lightroom, clicked PV2012, then saved a preset (does ACR support presets?) checking only tone/point curve, then using a text editor, converted it to the format required in DNG Profile Editor (recipe), and inserted it into a recipe file.
On the other hand, you can accomplish something close to the linear equivalent point curve using -contrast.
Found it - replace tone curve in dcpr file (DPE recipe) with this and you've got linear equivalent:

LR4.1 - Tone Curve - how to adjust individual RGB channels?

Hi,
I am having trouble figuring out how to adjust the curve of individual RGB channels. I am assuming the LR4 Tone Curve works like the PS Curves dialog with the channel dropdown.
The LR4.1 Help says:
To make adjustments to individual points on the tone curve, choose an option from the Point Curve menu, click the Edit Point Curve button , and do any of the following:
Choose an option from the Channel pop-up menu. You can edit all three channels at once, or choose to edit the Red, Green, or Blue channel individually.
When I click the little icon in the lower right corner of the Tone Curve panel, the panel shrinks so that I don't see the Regions sliders. If I click again, they are visible again. I can't find where to select one of the three indvidual channels.
The Help refers to "the Point Curve menu." Where is the Point Curve menu? Is the Point Curve different from the Tone Curve?
If I right-click (Windows) in the curve dialog, the context menu has a Show Info option. I click it on/off and don't see any change or any info. Where should I be looking for info?
Thanks for any help here.
John

Good morning John,
The point curve is the one without the sliders. The adjustments for the individual channels are only available with
PV2012. You must be editing a file with PV2010 or 2003. When in PV2012 you will see " Channels: RGB" below the curve window. Click on the doule triangles following the RGB
to pick the individual channel.

1 of 5 custom tones won't work with 'Text Tone'

I have managed to create 5 custom tones that are now on my iPhone 5. All five of the tones work for the 'Ringtone' but only 4 out of the 5 work for the 'Text Tone'.
This is more about a challenge to find the reason than anything else, because I can get by without the the 5th one working for the 'text tone', but it happens to be the one that is the most relevant for the 'text tone', being "I've gotta get a message to you" by the Bee Gees.
When I select this particular tone for the 'text tone' the phone does not make a sound, but it vibrates as I have the 'Vibration' setting set to 'Alert'.
So, does anyone want to take up the challenge to solve this situation?

Thanks for the advice. I re-did this particular tone for a length of 25 seconds and it now works. Weird that the other 4 work @ 30 second lengths. Anyway, thanks again, as I wouldn't have done this without your reply.

How do I set a preset in LR to import all files from my computer with a Medium Tone Curve?

I edit a file in PS, and LR informs me that the "metadata for the file has been changed." I opt for import settings from disk (my changes), but in doing so the file is always rendered with a linear tone curve. What I am seeking is to have the file that I've been working on PS, be with the same rendering in LR.
Thank you,
S

I just followed your workflow. In other words I used the "edit in" option to send an image to Photoshop where I made a significant change in the tone curve. Then I saved that image, which returned to Lightroom. The Lightroom tone curve still displayed as a linear curve. In other words it didn't reflect the changes that I made in Photoshop. However the image itself displayed the changes that were made. So apparently saving your PSD in Photoshop will not force Lightroom to display the Photoshop changes. As far as Lightroom is concerned, that is the new linear curve. The only curve adjustments you will see in Lightroom are the ones made using Lightroom.
To summarize what I'm trying to say, whatever you change the curve to in Photoshop becomes the linear curve in Lightroom. Sorry that I am so poor with words sometimes.

I am working in the Develop module of Lightroom 5 and have accidentally bumped a setting and lost the Basic menu and the option to retrieve it. "Tone curve" is directly under the tool bar now. How can I retrieve the "Basic" menu?

How can I retrieve the "Basic" menu on Lightroom 5? I accidentally bumped something while working in the Develop module of Lightroom 5, and now the Tone Curve menu is directly under the Tool Bar, with no option to click on "Basic."

Right-click on Tone Curve and choose basic again or press Ctrl+1 in Develop.
